Application filed March 31, 1917. Serial No. 158,791.

To all whom it may concern Be it known that 1, WILLIAM M. MITCHELL,

' a citizen of the United States, and a residentof Louisville, county of Jefferson, and State of Kentucky, have invented certain new and useful Improvements in Anticreepers for Railroad-Rails, of which the following is a specification.

' The invention relates to anti-creepers or rail anchors for preventing the creeping or longitudinal movement of railroad rails and seeks to provide a simple, inexpensive and effective anti-creeper or rail anchor which will remain solidly in position on the rail under varying working conditions.

Rail anchors now in use, in order to avoid perforating or otherwise weakening the rail, are held in position by a friction grip of one sort or another and are liable to work loose under the severe working conditions to which they are subjected. The present invention seeks to overcome these ditliculties and provide a rail anchor adapted to abut against the side of a tie and which is solidly united to the rail by welding or fusing without weakening the metal body of the rail. The invention also seeks to provide a rail anchor of simple form which can be manufactured and installed at low cost. The in Vention consists in the features of improvement hereinafter set forth, illustrated in the preferred forms in the accompanying draw ings, and more particularly pointed out in the appended claims.

In the drawings Figure 1 is a perspective view and Fig. 2 is an end view of the preferred form of the present invention:

Fig. 3 is a side elevation of a modified form; and

Fi at is a )lan view thereof.

b u u The anchor shown in Figs. 1 and 2 is extremely simple and inexpensive and can be readily forged or shaped from a short section of 'a fiat bar of wrought iron or steel by twisting the same between its culls to form 21 depending, tie-engaging abutment 9 and a rail-engaging portion 10 at its upper end, which is arranged at right angles to and in rear of the front. tie-engagingface of the abutment 9. The rail-engaging portion 10 of the anchor is adapted to be securely fused or welded to the edge portion of the rail base, and, preferably, is offset at its upper end to thereby form a shoulder-'11 which extends beneath the edge of the rail base. The intermediate twisted portion 12 serves as an inclined strengthening brace between the rail and tie-engaging portions of the anchor. I

The form shown in Figs. 3 and 4 can be readily forged from a short section of round bar of wrought iron or steel and coinprises a tie-abutting portion an upwardly or rearwardly extending. brace or body portion 6. and a rail-engaging portion disposed at right angles to the abutment and comprising a shoulder T that extends beneath the edge of the fail flange and? lip S which extends over the vertical face of the rail flange. This form can beshap'ed or forged. as stated, from a short section of a round bar by distorting orfott'setti'ng the opposite ends of the bar section to form the tie and rail-engaging portions which are connected by the intermediate bracing or body portion.

Either form of the improved anchor can be readily secured to one of the base flanges of the rail by welding or fusing, and either before or after the rail is placed in positioI in the track. Preferably, the anchor is t pplied to rail already in place in the track, and when this is done, a portion of the base flange adjacentthe tie is heated nearly to the fusion point by suitable means, such as a portable oxyacetylene torch. The anchor-is then applied in position, and the adjacent engaging portions of the anchor and rail are fused together by aid of the welding torch. Preferably, also, fillets of metal fused from a steel rod connect adjacent portions of the rail base and anchor, such fillets being solidly united or incorporated with the metal of the connected parts. In this way, the anchoris solidly and permanently united with the rail without indenting or otherwise weakening the metal body thereof. Qbviously, the anchor Lad car that might otherwise break 0E or destroy the anchor.

It is obvious that changes may be made in the details set forth without departure from the essentials of the invention, as defined in the claims.

I claim as my invention 1-. A one-piece rail anchor forged or shaped from a short section of substantially straight bar by distorting or offsetting the opposite end portions thereof to form a depending tie-engaging abutment, an upper rail-engaging portion dlsposed substantially at right angles to said abutment and adapt ed to be permanently fused or welded to one edgeot' the "rail base, and an intermediate bracing or body portion between said abutment and said rail-engaging portion.

2. A one-piece rail anchor comprising a messes metal bar twisted between its ends to form" tie-abutting and rail-engaging portions and haying its upper end ofiset to provide an upwardly projecting lip and an inwardly projecting shoulder. 4. A onepiece rail anchor shaped or forged from a short section of metal bar by distorting or offsetting its opposite end portions to form a tie-engaging abutment, an upper rail-engaging portion and an intermediate bracing or body portion, said upper' rail-engaging portion having an up- "ardly projecting lip andan inwardly projecting shoulder.
